[jitsi-users] Chat identities are mixed

I've noticed a weird behavior with the edition mode of the chat window that leads to mix messages of both users.
I looked at the opened issues but I did not found matching bug, thus I apologize if it's already a known bug.

To reproduce:
- user A sends a message
- user A pushes the up arrow to start editing the message
- meanwhile user B sends a message
- user A validates its edited message and it is displayed in the chat window.
- then if user A sends a new message, the message is displayed as a user B message in both windows.

Jitsi version is 2.6.5390 with OTR enabled.

Does anyone already noticed this bug?
